The expanded 1978 group without guitar but adding Michel Berckmans (oboe, bassoon) and Daniel Denis (sparsely added percussion) both on leave from Univers Zero. These are long, dynamic and highly concentrated pieces, filled with kinetic energy and coiled restraint; intensely musical, never obvious and they exploit the full resources of their instrumentation without ever abandoning the realm of tonality and metre. A fine work. Sorry about the price but it's a Japanese limited art edition..Last few copies..
